I've started playing with setting up a "production" version of PieFed. I have a few questions. I'm hoping someone can help. 1. Can I use S3 buckets for media? I use Wasabi S3 for my other Fediverse servers. Can I use them with PieFed? 2. Regarding the BOUNCE_ADDRESS settings in the .env file, what if I leave them all unfilled? Will the email bounces simply come back to the inbox of the sending email address? This is my preferred scenario. 3. The instructions have, "If BOUNCE_* is configured ...". Where is it configured? If I don't provide bounce addresses, do I need to care about this configuration? 4. For production, do I change MODE to MODE='production', or something else? Is it case-sensitive? 5. What is the SENTRY_DSN variable? 6. What happens if I set MAIL_ERRORS=True? Thanks, much! I'm sure I'll have more questions.
